Cardiovascular and Resistance Equipment
Biodex, System 4 Pro
The Biodex is a multi-mode computerized robotic measuring instrument designed to measure muscle strength. It measures muscle strength by applying constant resistance against muscles in repetitive motions quickly and as powerfully as possible.
If test results show muscle weakness (compared with your same age and sex comparison group) strengthening exercises may be prescribed. The test may be repeated periodically to monitor how strength is improving as a result of a strength training intervention program.
We use the Biodex:
- to assess strength of muscles around joints
- as part of a rehabilitation exercise to improve the strength of various joints
- There are 5 modes that can be used: Isokinetic Resistance, Reactive Eccentric, Passive Motion, Isometric, Isotonic
PORTABLE GAIT ANALYSIS SYSTEM
CIR System Inc. GAITRite System
The GAITRite measures how a person walks. It measures gait patterns for both time (temporal) and space (spatial) through pressure sensors in the mat. The software changes the information into foot placement patterns and overall gait patterns.
Research participants can be assessed with or without shoes and using walking aids such as crutches, walkers, or canes. One example: we create a simulated crosswalk scenario and ask participants to carry different loads (a full grocery bag or an open umbrella) to measure changes in gait and balance patterns.
We use the GAITRite:
- to provide valid and reliable walking measurements such as footfall patterns, step length, cadence, and speed.
- to measure changes in walking or gait patterns through replication of real life scenarios.
AIR-RESISTANCE FITNESS EQUIPMENT

FUNCTIONAL NEAR INFRARED SPECTROSCOPY
Functional near infrared spectroscopy is a non-invasive system that can be used to measure the amount of blood oxygen changes. It assesses the changes in absorption of light emitted by the probes in the cap. While this system can be used for different tissues (muscle, tendons), our system is specifically for measuring brain activation. Our system is portable and mobile, so we can tell what parts of the brain are being used during tasks such as reaching or walking.
We use this system to:
- understand the recovery of the brain after a traumatic brain injury or stroke or changes with aging
- determine whether our treatments are affecting the function of the brain
Motek Medical, M-Gait
Motek Dual-belt Treadmill is a unique treadmill that has two belts, one under each leg that can be set at different speeds or different directions. When the two belts are not running evenly, this disturbs the walking pattern of a person. Healthy people can usually adjust to these perturbations with ease, but this is not the case for people who may have walking difficulties due to disease or aging.
We use the Dual-belt treadmill combined with an overhead safety harness:
- to assess the coordination of walking and how people learn to adapt their walking patterns
- to understand how injury, disease or aging affects the coordination of walking

HIGH RESOLUTION PERIPHERAL QUANTITATIVE COMPUTER TOMOGRAPHY
Scanco, XtremeCT HR-pQCT
The HR-pQCT evaluates bones down to the level of the tiny individual elements that nature configures in a way that makes bones as strong as possible. HR-pQCT measures bone density and quantifies the three dimensional geometry, strength and microarchitecture of bone at the lower arm (radius) and lower leg (tibia).
HR-pQCT is a research tool—not currently used in clinical practice. It goes beyond current clinical methods and assesses bone microstructure to provide new insights into bone strength and why some bones are more susceptible to fracture.
At the Centre we use the HR-pQCT:
- to measure the bone mineral density of the forearm and lower leg
- to assess the geometry, strength, and microstructure of bone in 3-dimensions
DUAL-ENERGY X-RAY ABSORPTIOMETRY
The DXA is the gold standard clinical instrument used to evaluate body composition and bone mineral density. The analysis compares your values to a large database of healthy individuals to provide you two “scores”—the T-score and the Z-score.
WHAT DOES A DXA SCAN TELL US?
The T-score compares your results with healthy young adults and the Z-score compares your results with individuals of the same age and sex. The DXA is also a powerful clinical instrument used to diagnose osteoporosis.
The Advanced Body Composition assessment feature produces colour images displaying the distribution of fat, lean mass, bone and fat mass index. The information is translated into an easy-to-interpret report for improved patient management and counseling.
Is it possible to book the DXA for a research project?
Yes, staff at the Centre would be happy to address any questions you may have, discuss potential applications for the DXA, and work with you to coordinate your project.
Please contact us at firstname.lastname@example.org.
Who can use the DXA?
Local, national, or international Researchers from:
- Academic institutions
The primary use of the DXA is for health research, however researchers in other fields are welcome to submit a project proposal.
WE USE THE DXA
- to assess hip and spine bone mineral content and density.
- to evaluate total body, bone, fat and muscle mass.
